What Perplexity Does
Perplexity AI is an AI-powered research and answer engine. Unlike ChatGPT or Claude, Perplexity searches the web in real time and provides cited, sourced answers. Think of it as Google Search meets AI.
What We Tested
We used Perplexity daily for two weeks for fact-checking, topic research, product comparisons, news summaries, and technical questions. We compared results against Google Search and ChatGPT.
What Works Well
- Citations: Every claim linked to its source. For research and fact-checking, this is invaluable.
- Current information: Searches the web in real time. Ask about something that happened yesterday, and it finds it.
- Focus modes: Restrict searches to academic papers, Reddit, YouTube, or specific sources.
- Clean interface: No ads, no SEO spam. Direct answer with sources.
- Follow-up questions: Ask follow-ups in the same thread with full conversation context.
What Falls Short
- Creative writing: Not designed for content creation.
- Coding: Not a replacement for Cursor or Copilot for development work.
- Depth vs breadth: Excels at scanning many sources quickly rather than deep analysis.
- Source quality: Sometimes surfaces low-quality sources alongside authoritative ones.
Perplexity vs Google vs ChatGPT for Research
Google gives you raw links — you read multiple articles yourself.
ChatGPT gives synthesized answers without citations — cannot verify easily.
Perplexity gives synthesized answers with citations — best of both worlds for most research tasks.
Pricing
Generous free tier with standard searches. Pro at $20/month unlocks more searches, multiple AI models, file upload, and higher limits. Free tier is genuinely useful for most casual users.
The Verdict
Perplexity earns an A because it does research and fact-checking better than any other tool. The citation system fundamentally changes how trustworthy AI answers feel. If you do any kind of knowledge work, Perplexity should be in your toolkit.
